Yellow is tough with a beige and since your stucco is beige, the yellow isn't the best shade for your home.

Ideally all the trim around the bay window, the door and the half circle window are the same color when you are finished. Since your eave is light brown, matching the eave is probably ideal.

A full glass brown storm door is likely the best choice to work with all that so the door color could come through when the storm door is shut . . and then, choose a door color that you love but also will look good with the taupe house. Eggplant, red, terracotta, a cottagey sage green would work too.
